CoughDrop uses the text-to-speech engine of your device to generate voice output. Some buttons can have recorded audio but most will use text-to-speech. CoughDrop lets you select from any of the TTS voices that are provided by your current system. Voice settings are a per-device setting since they can vary across multiple devices and systems.
